User experience results from the interaction between a product and a user in a context. It is well-established that environmental context influences product perception and can even drive preference, especially when it is coherent with the product. However, there exist few studies testing the same product in different user experiences, where context changes but is not the only factor that does. By testing the same product (shampoo) with two scents in three different contexts, the aims of the study were to 1) characterize the influence of environmental context on sensory perception of the shampoo, 2) evaluate the impact of context on scent and overall product evaluation, and 3) to evaluate whether scent-context congruence influences shampoo evaluation, perception and associated benefits. To achieve these objectives, two shampoos sharing the same formula and differing only in their scents were evaluated by 256 women. Participants were split into three contexts: Home, Hotel and Hair Salon. A hairdresser was involved in the last context. Throughout the experiment, participants rated their emotional states, product liking, performance and assessments of the scents. Results confirmed that context influences user perception of haircare experience and depends on the user’s active or passive usage of the products. Moreover, context influences the projected benefits of the shampoo as well as the emotional state of users. The results are discussed in terms of multisensory coherence of the olfactory stimulus in relation to immersion characteristics. Taken together, the results emphasize the need to consider the holistic experience when evaluating beauty experiences.

现实生活环境对护发产品的用户体验、气味感知和感知性能的影响

用户体验是产品与用户在上下文中交互的结果。众所周知，环境背景会影响产品感知，甚至可以驱动偏好，尤其是当它与产品一致时。然而，很少有研究在不同的用户体验中测试同一产品，其中环境发生变化，但并不是唯一的因素。通过在三种不同的环境中测试具有两种气味的同一产品（洗发水），研究的目的是 1) 表征环境环境对洗发水感官知觉的影响，2) 评估环境对气味和整体产品的影响评估，3) 评估气味-背景一致性是否影响洗发水的评估、感知和相关功效。为了实现这些目标，256 名女性对两种配方相同、仅气味不同的洗发水进行了评估。参与者分为三个环境：家庭、酒店和美发沙龙。最后的情况涉及到一名理发师。在整个实验过程中，参与者对他们的情绪状态、产品喜好、表现和气味评估进行了评分。结果证实，环境会影响用户对护发体验的感知，并取决于用户主动或被动使用产品。此外，环境会影响洗发水的预期功效以及使用者的情绪状态。根据与沉浸特性相关的嗅觉刺激的多感官一致性来讨论结果。综上所述，结果强调在评估美容体验时需要考虑整体体验。
